VAT Calculator
Add VAT or GST to a net price, remove it from a gross total, work back from the VAT amount or find the rate from a receipt. Rate presets for the UK, the EU, the Gulf, India, Canada, Australia and Latin America, a multi-item invoice with mixed rates and a country comparison.
How it works
Add VAT: VAT = net × rate, gross = net × (1 + rate) · Remove VAT: net = gross ÷ (1 + rate), VAT = gross − net = gross × rate ÷ (1 + rate) · From VAT amount: net = VAT ÷ rate · Find the rate: rate = (gross − net) ÷ net × 100
VAT (value-added tax) and GST (goods and services tax) are a percentage of the net price. To add VAT, multiply the net price by the rate and add the result, or multiply by (1 + rate) in one go: 1.20 for 20%. To take VAT out of a price that already includes it, divide by (1 + rate). Subtracting the rate from the gross price takes off too much, because the tax was charged on the smaller net figure. At 20% the VAT is exactly one sixth of the gross price, and at 5% it is one twenty-first. If you only know the VAT on an invoice, divide it by the rate to get the net price. If you know the net and gross prices, the rate is the difference divided by the net price, and the calculator checks it against the rate you expected. Pick a rate preset (UK, EU, Gulf, India, Canada, Australia, Latin America and more) or type your own rate. For India the result is split into CGST + SGST for sales within a state or IGST between states; for Canada, into the federal and provincial parts. Turn on Several items to type an invoice line by line with different rates per line. You get a VAT-by-rate summary like the one on a VAT invoice, and a table showing the same price at other countries’ standard rates.
Worked example
A £500 net price at the UK standard rate of 20%: VAT = 500 × 0.20 = £100 and the gross is £600. To remove VAT from £600, divide by 1.20 to get £500 net, so the VAT was £100. Taking 20% off £600 gives £480, which is wrong. An invoice that shows £35 of VAT at 20% has a net price of 35 ÷ 0.20 = £175 and a gross of £210. In India, ₹1,000 at 18% GST is ₹180 of tax: ₹90 CGST + ₹90 SGST within a state, or ₹180 IGST between states. A receipt with a net price of 80 and a gross of 96 has a rate of 16 ÷ 80 = 20%.

Frequently asked questions
How do I remove VAT from a price?
Divide the gross price by (1 + rate). At 20%, £120 ÷ 1.20 = £100 net, so the VAT is £20. Do not subtract 20% of the gross: that gives £96 and removes too much, because the VAT was worked out on the £100 net price. A quick check at 20% is that the VAT is one sixth of the gross price.
How do I find the net price from the VAT amount?
Divide the VAT by the rate. If an invoice shows £35 of VAT at 20%, the net price is 35 ÷ 0.20 = £175 and the gross is £210. Choose From VAT amount and the calculator does this for you.
What are the VAT rates in the UK and the EU?
The UK charges 20% standard, 5% reduced and 0% on zero-rated goods. As of January 2026 the EU standard rates run from 17% in Luxembourg to 27% in Hungary: Germany 19%, France 20%, Spain and the Netherlands 21%, Italy 22%, Ireland and Poland 23%, Finland 25.5%. Most countries also have reduced rates for food, books and some services. Rates change, so check the current one before you invoice.
What are the GST rates in India?
Since 22 September 2025 most goods and services fall into a 5% or 18% slab, with 40% for luxury and sin goods and 3% for gold and jewellery. Within a state the tax is split equally between CGST and SGST; between states it is charged as IGST. The calculator shows both.
Is VAT the same as GST or US sales tax?
The arithmetic is the same: multiply to add the tax and divide by (1 + rate) to remove it. VAT and GST are collected at every stage of the supply chain, and businesses reclaim the VAT they pay on their purchases. US sales tax is charged once, at the final sale. For US states use the sales tax calculator.
How do I work out VAT on an invoice with several rates?
Work out the VAT for each line at its own rate, then total the VAT for each rate. Turn on Several items and type one line per item, adding a rate like "0%" to the lines that differ. The calculator lists every line and gives the totals by rate.
